SIGHT FOR FIREARMS.

Specification of Letters Patent.

Patented Feb. 7, 1922.

T0 all whom it may concern.'

Be it known that I, FRED WILLIAM GOR- DON, of New York city, in the county of New York, and in the State of New York, have invented a certain new and useful Improvement in Sights for Firearms, and do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to an improvement in sights for rearms and more particularly gunsights adapted to be adjusted manually according to the range.

The object of my invention is to provide a sight in which the parts are screwed together so that they cannot become accidentally detached from one another. A further object is to provide an adjusting mechanism for the sight so constructed that the sight may be adjusted for different ranges and the range indicated may be readily observed by the user of the firearm while he is sighting same. A further object is to arrange the parts so as to prevent the entry of dirt and grit between the same. A further object is to arrange the clicking mechanism so that dirt and grit may not enter the same and so that the parts will not be subject to any great degree of wear. A further object is to arrange the parts so that they may operate easily and particularly to arrange the yoke for carrying the sighting aperture in such a manner that the yoke is accurately guided in the desired direction without any possibility of the parts binding. A further object is to provide an adjustment for windage of an advantageous type.

While my invention is capable of embodiment in many different forms, for the purposes of illustration I have shown only one form thereof in the accompanying drawings, in which- Figure 1 is a plan view of a gun equipped with a sight made in accordance with my invention;

Figure 2 is a side elevation of the same;

Figure 3 is an enlarged side elevation of the same, partly broken away;

Figure 4 is a vertical section taken on line 4-4 of Figure 3;

Figure 5 is a transverse section of a detail, and

Figures 6 to 13 are views of details.

In the drawings I have shown a gun having a stock 1 which may be of any suitable type and provided with any suitable tiring mechanism. On the stock 1 there is located a gun barrel 2. On the side of the stock 1 there is located a disc 3 which is attached to the stock by screws located in holes 4 carried by the disc. Said disc 3 is furthermore provided with a plurality of holes 5 to lighten the same as far as possible. In the disc 3 there is a vertical dovetail recess 6 to receive a leg 7 of a yolk 8, said leg having bevelled edges and said yoke having a leg 9 with bevelled edges on the other side of the gun, which leg 9 is loosely guided in a dovetail recess 10 in the side of the barrel. In the leg 7 there is a shouldered slot 11 having at the lower end thereof an enlarged circular opening 12, said slot 11 being provided to receive a screw 13 having a screw threaded end 14 engaging with the disc 3 and an annular recess 15 to permit the screw to slide in the slot 11. The diameter of the main body of the screw 13 is the same as the diameter of the hole 12 while at the annular recess 15 the screw 13 is of the same diameter as the narrower portion of the slot 11. The flange formed on the end of the screw 13 by the recess 15 prevents the disengagement of the screw 13 except when the screw is opposite the hole 12. Said leg 7 of the yoke 8 furthermore, carries a pin 16 which engages with a spiral slot 17 in a disc 18 attached by screws 19 to a range indicating disc 20. The screw 13 passes through the cent-res of the discs 18 and 20. The disc 20 is provided with a knurled edge 21 so as to permit the same to be turned manually. Said disc 20 furthermore has a bevelled edge 22 carrying a series of numbers 23 which indicate the elevation of the sight and therefore the range by cooperation with a stationary mark 24 on a bevelled surface 25 carried by the disc 3. On the inner face of the disc 18 there are a series of radial notches 26 to cooperate with a clicking plunger 27 having a cylindrical hole 28 carrying a spring 29. The plunger 27 is located in a cylindrical recess 30 in the gun barrel 2, and has a knife edge 31 to engage with the radial notches 26. At its top the yoke 8 has a recess 32 to receive a sliding scale 33 having slots 34 to receive screws 35, screw-threaded into the top of the yoke 8 in such a manner that said scale 33 may be adjusted. Cooperating iii.

with said scale 33 there is a sliding eye-piece 36 which is provided with a flange 37 to be received in a slot 38 in the top of the yoke 8. Said sliding eye-piece 36 has agtransverse l/opening 3Qdthrough which passes aiadj"fist-` ing screw 40 having two sleeves 41 and 42 screw-threaded thereon and provided with outer screw-threaded surfaces so as to engage with inner screw threads 43 formed in the ends of the hole 39. Said rod 40 furthermore has a shoulder 44 to engage with the inner side of a bracket 45 attached by screws 46 to one side of the yoke 8. Said bracket 45 has a transverse opening 47 through which the rod 40 passes and beneath the opening 47 there is a pin 48 to engage with a hole 49 in a clicking disc 50 having spurs 51 to engage with a notch 52 in a knurled head 53 adapted to be secured by a screw 54 to the end of the rod 40. The sliding eye-piece 36 has a sighting opening 55 in which there is secured at the front a sleeve 56. At the rear there is provided a pivoted light-reducing ring 57 having a sighting opening 58 smaller in diameter than the sighting opening 55. The light-reducing rin 57 has downwardly directed ears 59 provided with a hole 60 through which a pin 61 passes, said pin being carried by the sliding sight 36 in openings 62.

While the gun is being sighted as, for example, while it is being held to the shoulder, the user of the gun will have in full sight the series of numbers 23 and the stationary mark 24, so that he can by turning the disc 2O adjust the sight according to the range. The rotation of the disc 2O causes the yoke 8 to be elevated or lowered through the engagement of the pin 16 with the spiral slot 17. If the light is bright, the pivoted ring 57 will be in an elevated position so as to attain the greatest degree of accuracy possible by using the smallest usable opening for sighting. If the light is not bright, however, the pivoted ring 57 will have been moved into a horizontal position so as to no longer be in front of the opening 55. dg-

which guides tthe usli,dingey`efpiece. 36 to one side'orthecther as shown by comparison with the scale 33. It will be noted also that the scale 33 may itselfy be adjusted if it should be found for any reason that the gun requires a permanent correction laterally.

While I have described my invention above in detail, I wish it to be understood that many changes may be made therein without departing from the spirit of my invention.
